Re: How to: Check SSL version Numbers remotely

[thomas springer <tuevsec () gmx net>]

Depends, what you mean with Version:

1) Version of SSL-Software/Libs (e.g. OpenSSL 0.9.7e or GnuTLS 1.4.0)
Most of thes are linked with Server-Software, e.g. Apache. You might
grab banners, especially Apache often reports the mod_ssl or
openssl-Versions and check the capabilites of the SSL-Lib (Supported
Protocols and Ciphers). These might give you a hint about software and
version, but neither of these will give you a really trustworthy
version-info of the used ssl-libs. I don't know any relyable method to
check this remote.

2) Version of default (and other supported) SSL-Protocols (e.g. SSL 2.0,
SSL 3.0, TLS 1.0, TLS 1.1)
Use GnuTLS, OpenSSL, a Foundstones SSL-Digger (beware: good, but
ancient!) or the SSL-Check at www.serversniff.net.

3) Version of default (and other supported) Ciphers (e.g. 3DES, AES 128,
RC4 ...)
Use GnuTLS, OpenSSL, a Foundstone SSL-Digger or the SSL-Check at
www.serversniff.net.
